The doubler is integral of the skin, will it not be detailed in the lay-up then?
Aside of that, is the doubler damaged?
The doubler is the same material as the skin. If it is damaged, can you not use the existing doubler, to look at the ply orientation by taking it apart?
Otherwise, the main...
On analysing repairs on the A380 beams, we are presented with Torsional plastic bending, as a means of substantiation. This led to a request for the reference text for this. This was provided as "Behaviour of inelastic materials" by James O Smith.
A quick book search shows this was printed by...
These drawings are proprietory data of Goodrich Aerostructures now.
I Used to do stress analysis of the repairs on these sleeves, or Translating Sleeve, that you are talking about.
I would recommend contacting Goodrich direct on the topic.
It would help to know if your looking at repairing...
There are calculations done on closeouts, such as powerplant panels, which shows the load is low. Indeed on the A380 Reverser, the panels don't have a closeout.
I'm assuming your talking of sections going from monolitihic to sandwich panels, and the closeout being the portion between?
In the...
Most of my composite work, which involves deducing Kt's, is based on in-house practices.
Perhaps this can be of help.
Developing the Reduced stiffness matrix for your laminate, you can apply this in a calc for whitney point stress methods, to arrive at a kt. This is more useful for holes, or...

In answer to your question, which is, how to compute Edge Margin, it is the same for the fastener and plug, assuming they are both have incidental centrelines, which is a fair assumption.
If it is to get a joint shear capability you are actually asking for,then all said before is applicable...
